33 COE Rod Silver Unobtainium

33 COE glass rod by Northstar

NS-120 Silver Unobtainium is also a dark blue sparkle that has silver in it. It is well suited for stringer application and blown work. It is easily worked and can take a lot of heat. To keep the color the most vibrant, work in a neutral to slightly oxidizing flame. Try to avoid deep encasement that may cause cracking. When worked in an oxidizing flame, it stays a dark blue color with wispy hues of silver over it. If reduced, the color does not show much sparkle but still has many vivid colors.
